BREAD-RAISER.

SPECIFICATION'forming part of Letters Patent No. 366,050, dated July 5, 1887.

Application filed September 23, 1886. Serial No. 214,392. (No model.)

To all whom it may concern.-

Be it known that I. CHARLES JEFFERSON WALTHALL, of Petersburg, in the county of Dinwiddie and State of Virginia, have invented a new and Improved BreadRaiser, of which the following is a full, clear, and exact description.

My invention is an apparatus for raising bread or similar dough, and has for its object to effect the same in a simple, cheap, and expeditious manner.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a perspective view of my apparatus,partly broken away in section, and Fig. 2 is a central transverse section through the same.

In the construction of my bread-raiser I usuall y employ a rectangular box, A, adapted to be mounted upon legs a, a suitable distance above the surface upon which it is designed to rest,.and provide the said box with a detachable lid, 13, whose inner surface is concaved or hollowed out to adapt the said lid when detached for use as a doughtray. The box A is further provided with a-door, 1), extending from endv to end at the front and hinged to said box near the bottom, to swing horizontally downward. In the door, usually to one side of the center,I provide asightopening, O, fitted with an ordinary glass pane, and at the back of this pane, in full view from the front, a thermometer, D, is usually attached to the inner side of the door b, just above the said sight-opening O, to extend vertically downward. At a convenient point within the box A a perforated or slotted shelf, E, is provided,

' adapted to rest unattached upon suitable supports,d, secured to the sides and back of said box. Air-openings e are ordinarily made at the ends of the box,near the top thereof,- covered upon the inside with fine wire-netting. The bottom of the box A consists of a rectangular air-tight metal tank, H, provided with horizontal flanges h, by which it is secured to the bottom edge of said box by nails, screws, or other equivalent fastenings, and an angular projecting neck, It at one end, provided with a proper stopper. Through this neck water is poured into said tank, with which fluid it is adapted to be filled.

To complete my bread-raiser for operation, a lamp, K, is so placed under the box that the flame therefrom will come in contact with the tank H. I

The operation is as follows: The dough, after being prepared in the tray B,is transferred to a pan or other convenient receptacle, and,.the said receptacle thereupon placed in the box A upon the shelf E. If it is desired that the bread rise quickly, hot water is poured into thetank H if not,cold water is employed. The lighted lamp K is then placed under the tank. As the tank and water become hot a constant and uniform heat is obtained within the box, and the dough thereinwill quickly rise and remain perfectly sweet until taken out. gases that may be generated in the boxare passed out through the ventilating-holes c, and the thorough ventilation effectually prevents the dough from sweating or becoming sour. By means of the thermometer the state of the temperature can be seen at a glance. The heat should be kept up to about 95, although 90 or 85 will effect a satisfactory result; but more time is then required.

j The wood employed in the manufacture of my bread-raiser should be poplar or other sweet wood, as pine or oak impart a flavor to the dough.

I usually indicate by imprinting or pasting the word high upon the thermometer the maximum degree of heat requisite to obtain favorable results, as shown in Fig. 1.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

The bread-raiser comprising the receptacle having in its bottom a water-vessel, provided with a projecting angular neck, the slotted
